ABSTRACT

We present a retrospective analysis of surgical outcome of sinonasal malignant tumors. Overall survival (OS), disease-specific survival (DSS), local control (LC), and disease-free survival (DFS) were calculated in 32 patients. Prognostic factors for survival and functional outcomes were investigated. The median follow-up period was 70 months. At 5 years, OS, DSS, LC, and DFS rates were 0.722, 0.745, 0.851, and 0.707, respectively. Prognostic factors for poor OS were involvement of the frontal sinus (p = 0.023), T classification (T4, p = 0.025), surgical complications (p = 0.029), chemotherapy (p = 0.035) postsurgical infection (p = 0.043), involvement of the orbit (p = 0.048), histology (squamous cell carcinoma, p = 0.049), and radiotherapy (p = 0.043). Prognostic factors for poor DSS were radiotherapy (p = 0.030), chemotherapy (p = 0.036), positive surgical margin (p = 0.034), and T classification (T4, p = 0.050). LC was adversely influenced by surgical procedure (combined frontotemporal resection, p = 0.035) and positive surgical margin (p = 0.049). DFS was adversely influenced by positive surgical margin (p = 0.001). Prognostic factors for poor functional outcome were postsurgical infection (p = 0.039), postsurgical complications (p = 0.040), tumor location (maxillary sinus, p = 0.042, orbit, p = 0.0002), number of sinuses involved (number of sinuses involved was inversely proportional to functional outcome, p = 0.027), T classification (T4 p = 0.007), pathology (squamous cell carcinoma, p = 0.023), and chemotherapy (p = 0.048). Craniofacial resection was an effective surgical option.
